The content of marketing major includes human resources, finance, sales, logistics and other management contents in the field of management, with some hybridity. Insufficient cognition on the major and one's own psychological characteristics affects the optimal allocation of time during college years, which in turn affects academic performance and employment. Through questionnaire surveys of current students and interviews of graduated students majoring in marketing at Ningde Normal University, this paper analyzes students' academic and employment cognitions. Some lower-grade students majoring in marketing have vague cognitions about their major. In addition to the unclear cognitions about the major, like students of other majors, a certain proportion of students also lack clear cognitions about their own psychological characteristics. After students start learning marketing, it is necessary to improve their cognitions about the major through various means. Offering career planning courses in the first semester enables students to cognize the major and themselves earlier, so that they can engage in purposeful learning and training during college, which is beneficial for their academic development and employment.
